2 different types of systems, same sump?

[kattz]

I have a 150DD and a 300DD and the 300DD will be an SPS/LPS mixed tank, whereas I want the 150DD to house primarily nems/clownfish.

Can they both safely share the same system, or is this an issue?

Thanks,

Kevin

My 165 is SPS and Zoes. And my 29 is using the same sump [water] and houses my clown/anemone.
Many keep anemone's and clowns in the main tank with SPS.

So yes you can share the same water for a 450g total system.
